If you want a smart home hub that can connect to and control devices from different manufacturers, I'd focus on Matter, Thread, Zigbee, Z-Wave, and Wi-Fi compatibility rather than choosing a hub based on its app or brand alone.
The best choice depends on how many third-party sensors and devices you want to integrate, whether you want local control without the cloud, and how much automation flexibility you need.
The best smart home hubs to consider
1. Home Assistant Green
(Best overall flexibility)
Best for mixing brands, advanced automations, privacy, and long-term control.
Integrates a huge range of third-party products through software integrations.
Strong local control, customizable dashboards, and powerful automation rules.
Limitation: Zigbee and Z-Wave require compatible USB radios or other supported hardware.
Best for: enthusiasts who want one central brain for the whole home.
These are the strongest candidates for different needs, rather than a guarantee that every device will work with every hub. Protocol support and device-specific integration are separate issues.
What compatibility should you look for?
Technology
What it connects
Why it matters
Matter
Compatible devices across major ecosystems
Best starting point for newer cross-brand devices
Thread
Low-power sensors and smart devices
Requires a compatible Thread border router
Zigbee
Many sensors, bulbs, plugs, and switches
Common in affordable smart home devices
Z-Wave

What matters most when choosing
Technology
What it means for you
Matter
Helps compatible devices from different manufacturers work across ecosystems.
Zigbee
Common in battery-powered sensors, bulbs, plugs, and switches.
Z-Wave
Important for many existing door locks, contact sensors, and home-security devices.
Thread
A low-power networking technology used by many newer smart-home devices; a Thread border router is needed for the relevant network setup.
Local control
Lets supported automations work without relying on a vendor's cloud, though remote access may still need the internet.
These standards are complementary, not interchangeable. A hub that supports Matter doesn't automatically support every Zigbee or Z-Wave device, and compatibility may vary by device model and available features.
Let's narrow it down to your setup
The most useful next step is to match the hub to your existing hardware.
1. Which brands do you already have?
2. What types of sensors or wireless protocols do you use?
